Belimo LRB120-3 Actuator
The Belimo LRB120-3 Actuator is a field-proven solution for high-performance fluid control in demanding HVACR environments. Engineered as a 100-240 VAC non-fail safe actuator, this component provides reliable on/off and floating point control for characterized control valves (CCV). Delivering a consistent 45 in-lb torque, it is purpose-built for the precise regulation of chilled or hot water systems, supporting glycol concentrations up to 60%. As a non-spring return actuator, it reduces unnecessary power consumption, drawing only 2W during operation and maintaining a low 0.5W standby load. The integrated 3-foot appliance cable and 1/2-inch NPT conduit connector simplify electrical installation for technicians, while the NEMA 2 / IP54 enclosure ensures longevity in internal mechanical spaces. With a 90-second run time and an external manual override button, the Belimo direct-coupled actuator allows for efficient commissioning and manual system testing without requiring constant power.
Key Benefits for the Contractor- Universal Voltage Input: Operates on 100 to 240 VAC, making it a versatile choice for a wide range of commercial building power requirements.
- Maintenance-Free Operation: Features a brushless DC motor and electronic overload protection to ensure consistent performance over the service life.
- Simple Field Integration: The floating point control valve actuator design includes a selectable direction-of-rotation switch for easy site configuration.
- Efficient Power Profile: Optimized for low energy use, significantly reducing the transformer sizing requirements (4 VA) for large-scale installations.
- Pluggable Position Indication: Visual mechanical indicator allows for quick verification of valve status during routine maintenance cycles.
How do I manually move the valve if the power is out?
The unit features an external manual override button located on the top of the housing. Depressing this button disengages the gear train, allowing for manual positioning of the valve stem.
Can several LRB120-3 actuators be wired in parallel?
Yes, these units can be connected in parallel, but you must ensure the total power consumption and input impedance do not exceed the controller’s output ratings or transformer capacity.
Is this model suitable for outdoor installation?
The LRB120-3 is rated as a NEMA 2 / IP54 enclosure, which is intended for indoor use. For outdoor applications or environments with direct moisture exposure, a protective weather shield or a NEMA 4X rated enclosure would be required.
